VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 514,422, dated February 6, 1894.

Application filed March 31, 1893. Serial No. 468,604.. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM M. KELLOGG, a citizen of the United States, residing at St. Johnsbury, in the county of Caledonia and State of Vermont, have invented certain new and useful Improvements in Vaporizers; and

I do hereby declare the following to be 'a full,

clear, and exact description of the invention, such as will enable others skilled in the art to to which it appertains to make and use the same.

This invention relates to dishes for the vaporization of medicinal or, insect exterminating compounds.

L5 The object of the invention is to provide a vaporizer combining a construction which will permit of the free escape of the fumes arising from its contents, with provision for safety against spilling the fluid in the vapzo orizer should it become accidentally overturned, and means for easily and closing or sealing the same when in use so as to retain the medicinal properties of said compound.

The invention consists in the novel con- 2 5 struction of the vaporizer which will be fully set forth in the following specification and claim and clearly illustrated in'the accompanying drawings forming a. part thereof, of which- 3o Figure 1, represents a central vertical sectlon of my improved vaporizer. Fig. 2. is a similar view showing a slightly modified interior, which will prove of advantage only in the closing of the vaporizer. Fig. 3. is a plan 3 5 view of my improved vaporizer.

Similar reference letters denote corresponding parts.

I do not confine myself to a vessel of the proportions shown in the drawings, for one 0 more shallow in construction would serve as good a purpose in respect to the ready escape of the fumes from the contents, but the construction having substantially the proportions shown is preferable, to fulfill one im 5 portant function of my invention viz.-that of preventing the escape of the liquid if the vessel should be tipped over.

The exterior shell A, of the vaporizer, may

be of any desired form, that shown in the drawings being cylindrical, and this will be provided with a flat bottom B. To the interior, at or near the top of the shell A, I secure removably, by screw-threading or other suitable means the larger end of an inverted cone, and funnel shaped partition 0, extend- 5 ing two thirds of the distance more or less from the top of said shell to its bottom, the object of forming the partition removable is to enable the ready cleansing of the inner sides of the vessel. The lower end of said funnel shaped partition 0, is left open, and may be provided with an upwardly extending tube D, for the reception of a suitable stopple E, as seen in Fig. 2, or, the more simple construction in which the stopple is intro- 6 5 duced at the mouth 0, of. the funnel shaped partition 0, as seen in Fig.1,may beadopted.

The construction shown in Fig. 2, comprising the tube D, permits a more convenient manipulation of the stopple, but in other respects its advantages over that construction shown in Fig. l. are but slight. An important feature of my invention however is the perforated cap or cover F;--this permits the free escape of the fumes from the vaporizer by reason of the numerous fine openings f and still prevents insects from entering the same.

This vaporizer is designed for use in clothes presses, closets, bureau drawers, and like places where clothing and garments, on which. Buffalo-bugs and moths are accustomed to feed, are kept, and to keep in such places a liquid compound for their extermination in an uncovered vessel would be hazardous on account of its liability to be spilled, unless the vessel contained the inverted conical top or funnel shaped partition 0, and even such construction would hardly be feasible without the perforated cap F, to keep out the insects. I

When the receptacle is desired for use, the cap F, is first removed, then the stopple E, then the cap F, is replaced; but when the receptacle is not required to send forth the 9 5 fumes of its contents, the stopple E, will tightly seal the same.

The bottom B, it will be noticed is not flush with the lower edge of the shell A, but is set up a short distance from the bottom of said we shell, for the insertion of a bushing or false bottom I), as shown in Fig. 1. to be made of some flexible material, such as felt, to absorb moisture or leakage from the receptacle A, which might otherwise deface the article on which it rested.

Having described my improvements, what I claim is- In a vaporizer consisting of a receptacle provided with a perforated cover and having a conntersunken bottom containing an absorptive filling, said filling protruding below the lower edges of the receptacle and forming a resting surface therefor, said receptacle having also a reentrant, removable, frusto-conical partition provided with a central perforation, and in combination with said partition of an upwardly-extending tube lying Wholly within the receptacle and formingacontinuation of the said perforation, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
